Oil paint spray room

Abstract

The invention relates to an oil paint spray room. The oil paint spray room comprises oil paint spray room bodies, primary purification treatment devices, secondary purification treatment devices, a buffer container, an auxiliary water tank, a heat exchanger, a water pump and a controller. The oil paint spray room bodies communicate with exhaust fans, the exhaust fans communicate with the buffer container through the primary purification treatment devices, and the buffer container communicates with inlets of the secondary purification treatment devices. A circulating water pool is arranged below the oil paint spray room bodies. The oil paint spray room bodies are provided with water spray pipes, the water spray pipes communicate with the auxiliary water tank, the auxiliary water tank communicates with the heat exchanger and the water pump in sequence, the auxiliary water tank is located above the oil paint spray room bodies, and the water pump communicates with the circulating water pool. The secondary purification treatment devices are uniform in workload and high in efficiency and effectively reduce energy consumption of the whole waste gas treatment device. Concentrated collection and release are realized in the buffer container, adoption of multiple sets of waste gas treatment systems is avoided, the number of the secondary purification treatment devices is reduced, and thusequipment investment is saved, and only a small amount of equipment space is occupied.

Description

technical field [0001] The invention relates to the field of paint waste gas treatment, in particular to a paint spraying room with paint waste gas treatment. Background technique [0002] After many industrial products (such as auto parts and various optical cable equipment) are finished, the surface must be polished, sprayed with paint, and dried to form a finished product. The paint spray booth is used to spray paint for these industrial products. In addition to spraying on the workpiece, about 20% of the paint mist that is atomized during the paint spraying process will not be able to adhere, but will be free in the air. [0003] The existing treatment of paint waste gas in the paint room is usually to install a set of treatment system above the body of each paint room for treatment, and to set up a water circulation system below it to control the working environment around the body of each paint room. The paint waste gas is purified and absorbed. [0004] Among them, ...

AI Technical Summary

Problems solved by technology

The treatment system has the following problems: 1. The structure of the first-level treatment facilities is often too simple, and the waste gas treatment efficiency is not high; 2. When a production line is equipped with multiple paint rooms, each paint room is equipped with a One set of treatment system requires multiple sets of treatment systems, thus requiring multiple sets of secondary purification treatment devices

Such a paint treatment system will cause the workload of the secondary purification treatment device to be uneven due to the uneven and constant exhaust gas discharge of each paint room, resulting in waste of energy consumption, equipment processing capacity and investment; the secondary purification The processing device will occupy a large amount of equipment space; when a certain set of paint treatment system fails, the exhaust gas emitted by the corresponding paint room will not be treated, and the system reliability will be reduced

[0005] Among them, the water pump used in the water circulation system of the spray paint room is directly connected to the water spray pipe, and is transmitted from a low place to a high place, resulting in uneven water velocity from the water spray pipe, so the waste gas treatment efficiency is not high, and it is free in the air. Part of the paint mist in the water will be absorbed by the water curtain produced by the water curtain machine, but there is still a considerable part of the paint mist that cannot be absorbed and discharged into the atmosphere from the sewage pipe, causing serious environmental pollution.

In addition, the existing water circulation system used in the paint spray room cannot actively adjust the temperature of the sprayed circulating water, which has a bad influence on the absorption effect of paint exhaust gas
